My new yeast has arrived and is showing promise after 24 hours of rehydration. I've just fed it and I'm already noticing a difference in the smell.
There's a new loaf under way and I'm experimenting with the "no knead" system. Basically you mix the starter, water, salt and flour together and leave it for 18 hours. Then you fold, rest, shape and let it proof again before baking in a cast iron pot. I'm using Yogi again and already the dough is rising very well. I'm concerned that it's very soft and moist though.
